Combined type retainer for new energy automobile

Abstract

The invention discloses a combined type retainer for a new energy automobile. The combined type retainer comprises a first bearing and a second bearing, wherein the first bearing and the second bearing have the same structure; an annular rail is arranged in the middle of the circumferential side wall of each of the first bearing and the second bearing; balls with the same structure roll in the rail; a first steel ring and a second steel ring are connected with two sides close to each other of the first bearing and the second bearing; four inserting rods in an annular array are connected with the side, close to the first steel ring, of the second steel ring; four inserting holes in an annular array are formed in the side, close to the second steel ring, of the first steel ring; the inserting holes are in sliding fit with the inserting rods; movable grooves are formed in positions, above and below the inserting holes, of the first steel ring; and gear levers are in sliding fit with the interiors of the movable grooves. The combined type retainer enables connection between two retainers to be firmer to avoid a potential safety hazard, can automatically clean dust during the using process, improves the device sensitivity and is suitable for popularization.

Description

Technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a combined type cage for new energy vehicles. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as the power source (or the use of conventional vehicle fuels, the use of new on-board power devices), and the integration of advanced technologies in vehicle power control and driving. Cars with new technologies and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles. [0003] Chinese Patent Publication No. CN207093584U, a combined cage for new energy vehicles, proposes a combined cage for bearings. The combined cage can mount two cages together in the same position, so that the two The two cages can be deflected synchronously to improve the stability of machine operation. A spli...

AI Technical Summary

Problems solved by technology

A split design is adopted between the two cages. When a cage wears out and other problems occur, it can be replaced directly with a cage of the same type, so that each cage can realize its maximum use value, but the patent does not To solve the problem of the firm connection of the two cages, there will be certain safety hazards during use. At the same time, the cage will be covered with more dust during use, resulting in a decrease in its sensitivity. Therefore, in order to solve such problems, we A combined cage for new energy vehicles is proposed
